What's best to use - xylitol chewing gum, xylitol drops/candy, xylitol gel or simply xylitol sugar (powder)?

Since xylitol is the only truly active and effective ingredient, the following rule applies: the longer and more thoroughly mouth and teeth including the interstices are bathed in xylitol, the better and the more complete the effect. This means that the clear winner is xylitol sugar resp. More.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
